Hi,
I found that for DRI callback 'SwapContext' hook handler, seems no driver
interested with it, except for old glint video driver do real work in it.
Does it mean context switch concept outdated for current graphics hardware,
but I found that intel hardware has logical context save/store command for
these stuff? As I guess, context switch design strategy was taken out behind
background of old-style DMA graphics device such as GLINT. But how the
performance boost by using context switching rather than by reg-by-reg
emiting at that old time? Thanks very much.
Regards
